WELL-CLEANING MACHINE.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed m 1907. Serial at. 384,405-

To all whom it may concern: 7 I

Be it known that I, J ONAS HENRY Onowson, a citiaen of Cass and State ofTexas, have invented a new and useful Well-Cleaning Machine, of whichthe following is a specification. i I

This invention relates to devices for cleaning wells, cisterns and thelike and has for its object to provide a comparatively simple andinexpensive device of this character by .means of which mud, leaves andother deposits may be effectually removed from the bottom A furtherobject of the invention is to provide a well cleaning device including apair of spring actuated jaws provided with terminal scoops adapted toreceive the mud or other deposits, said cleaner being provided with anoperating rope'or cable so that the scoop containing the mud may beconveniently removed from the well.

A'further object is to provide the spring actuated jaws with adjustablespreader arms having their inner ends pivotally united and operativelyconnected with a depending rod or trigger adapted to engage the bottomof the well for moving the scoops to closed position.

A still further object of the invention is to generally impro ve thisclassof devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the mowing description, itbeing understood that. various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

In the accompanying drawings there is illustrated a side elevation of awell-cleaner constructed in accordance with my invention, the scoopsbeing shown in full lines in open position and in dotted lines in closedposition.

Similar numerals of reference indicate corresponding parts The improvedcleaning device forming the subject matter of the present inventioncomprises a pair of spring pressed jaws 5 and 6 preferably formed from asingle piece of heavy wire or other suitable material and having anintermediate portion thereof bent to forma horizontally disposed coil 7and its opposite ends extended laterally to form terminal bearingsurfaces 8 for engagement with the scoops 9. The scoops 9 are riveted orotherwise rigidly secured to the flat bearing I within the same.

14 of the spreader arms are p ivotally united and provided withvertically disposed stop lugs 15 which bear against each other when thearms are in operative or extended position and serve to hold the scoops9 in position to receive the mud or other deposits on the bottom of thewell when the cleaning device is lowered The inner ends of the sections13 and 14 are provided with fiat portions having elongated slots 16formed therein for the reception of suitable clamping bolts 17 wherebythe spreader arms may be lengthened or shortened so as to increase ordiminish the tension of the spring 7.. Dependingfrom the inner pivotedends of the spreader arms is a rod or trigger also preferably formed intwo sections 18 and 19. The section 18 of the triggerlextends throughthe pivoted ends of the spreader arms and forms the pivotal axis of thesame, said section being provided with an elongated loop 20 adapted toreceive the sections 14 of the spreader arms when the scoops 9 are movedto closed position, as shown by the dotted figure in the drawing. Thelower section 19 of the trigger is slidably mounted on the section 18andis provided with one or'more elongated slots 21 similar in constructionto the slots 16 and adapted to receive suitable clamping bolts 22whereby the trigger may be lengthened or shortened at will..

minal head 23 adapted to bear against the bottom of the well or cisternand force the pivoted ends of the spreader arms upwardly so as to causethe intermediate coils or spring to force the scoops 10 to closedposition.

Attention is here called to the fact that the abut-v ting faces of theshoulders 15 are slightly inclined or beveled so that when the spreaderarms are in extendedor operative position said arms will be arranged ata slight angle to each other and thereby lock the scoops 9 in openposition.

Extending through the spring coil or loop 7 is a yoke or stirrup 24 tothe terminal eye 25 of which is attached a link having a swiveledconnection 26. Secured to the upper end of the link is an operating cordor cable 27 by means of which the cleaner may be lowered into or removedfrom the well.

In operation the spreafder arms are extended laterally so as to causethe scoops to assume the position shown in full lines in the drawing andin which position the cleaner is lowered to the bottom of the well bymeans of the operating cord-or cable 27. When the head 23 of the triggerengages the bottom of the well or cistern the weight of the cleaner willforce the trigger upwardly and in doing so will cause the spring 7 tomove thejaws to the dotted line position shown in the drawing, As thejaws are moved to closed position the members 9 will scoop up the mud inthe bottom of the well so that by exerting a longitudinal pull on theoperating cable 27 the scoop containing the mud orv other deposits maybe conveniently removed from the well.

In order to set the device it is merely necessary to exert a downwardpull on the trigger when the spreader arms will be moved outwardly, thuscausing the scoops 9 to assume the position shown in full lines in thedrawin The device may be made in different sizes and shapes and may begalvanized, japanned or otherwise coated so as to prevent the same fromrusting.

From the foregoing description it is thought that the construction andoperation of the device will be readily understood by those skilled inthe art and further description thereof is deemed unnecessary.

Having thus described the invention what is claimed is:

1. well cleaning device including spring pressed jaws each provided witha scoop, spreader arms pivotallv connected with the jaws and pivotallyconnected with each other. and a depending trigger forming the pivotalcon nection between the inner ends of the spreader arms.

2. well cleaning device including spring pressed jaws having terminalscoops secured thereto. spreader arms havinga. their inner endspivotally connected and provided with ctr-acting slop shoulders andtheir outer ends pivotall' connected with the sprii jaws. and a triggerforming the pivotal connection between the inner ends of the springjaws.

It. well cleaning device including spring pressed jaws having scoopssecured to the free ends thereof, longitudinally adjustable spreaderarms pivotully connected with the jaws and having their inner endsoverlapped and providcdwith ctr-acting slop shoulders, and a triggerextending through the over-lapped ends of the spreader arms and forminga pivotal connection between the same.

4. A well cleaning device including spring pressed jaws provided withterminal scoops. spreader arms pivolally connected with the jaws andeach formed of a plurality of sections having their adjacent endsover-lapped and provided with elongated slots. clamping boltse.\'ten'din through said slots for locking the spreader arms in adjustedposition, and a trigger operatively connected with the inner ends of thespreader arms.
